The Santa Isabel Project (Nicaragua) is investigating domestic remains
from a supposed Postclassic/Ometepe-period regional center on the
shore of Lake Nicaragua. However, a suite of twelve C-14 dates from the
site suggests that the occupation predates the currently accepted time
range for the Ometepe period by several hundred years, calling into
question the periodization and associated cultural processes. This paper
reports and contextualizes those dates.
